ISTANBUL (Reuters) - Turkish fixed-line operator Turk Telekom said on Friday that it clinched a cooperation deal with Vestel after President Tayyip Erdogan called on Turks to use locally-made mobile phones instead of Apple’s iPhone.

Vestel will be able to use Turk Telekom’s sales infrastructure for its smart phones, the statement said, adding the campaign is expected to begin at the end of the year.
